Co-living rental investing means renting a house by the bedroom instead of by the door, with furniture and utilities bundled into the room rate. Done to spec, it produces cap rates north of 8% and cash-on-cash returns in the 15-25% range, according to Clara of Coliving Cashflow, who built one of the country’s largest co-living operators out of Boston before moving into coaching and new construction.
The catch is that it is not a mindset shift you can apply to any rental you own. It is a spec sheet: minimum square footage, a resident-to-bathroom ratio, a walk distance to transit, a drive time to job concentrations, and a local cap on unrelated adults sharing a dwelling.
What follows is that spec sheet, the return math behind it, the tenant profile and lease terms that keep rooms full, and the regulatory constraint that kills more deals than any other.
Key takeaways
- Screen properties at 1,200-1,300 square feet minimum with a 3:1 resident-to-bathroom ratio (4:1 is the ceiling) before you underwrite anything else.
- Underwrite to cap rates above 8% and cash-on-cash in the 15-25% range; Dallas rooms with private bathrooms rent in the $700-$1,000 band.
- Site within roughly a mile walk of public transit and 20-25 minutes of universities, hospitals, military bases or warehouse job concentrations.
- The binding legal constraint is the cap on unrelated adults per dwelling — four in Massachusetts, roughly three in New York — and it varies county by county in Texas and Florida.
- Hire property management on a fixed fee per unit rather than a percentage of rent, and train the PM specifically on co-living operations.

This article draws on an interview with Clara of Coliving Cashflow on the Investor Fuel Show, hosted by Mike Hambright. Watch or listen to the full interview.
Why Co-Living Cash Flows When Traditional Rentals Don’t
The math is simple arithmetic on the revenue line. A house that rents to one household for a single number can gross a multiple of that number when five rooms rent individually. In Dallas, Clara’s clients are getting $700 to $1,000 per room where the room has a private bathroom. Run five of those against a market rent of $1,500-$1,800 for the whole house and the gap is obvious.
The returns she cites for well-executed deals: cap rates north of 8%, running through 10, 11 and 12 — she has one operator who only buys at 12% or better — and cash-on-cash of 15% to 25%.
The second half of the argument is vacancy, and it gets less attention than it deserves. A single-family rental is binary. It is 100% occupied or 0% occupied, and when it turns, revenue goes to zero while the mortgage, taxes and insurance keep running. A five-bedroom co-living house does not have that failure mode. Three rooms out of five covers the base cost. The remaining two are margin.
That changes how you sleep at night more than it changes the spreadsheet. It also changes what a bad month looks like: a 20% revenue dip instead of a total stop.
The pressures pushing investors here are the same ones squeezing every rental portfolio right now — taxes up, insurance up, rates up, affordability down. Rent-by-the-room is one of the few structures where the revenue side moves enough to absorb that. It is not a financing trick. It is a different product sold to a different buyer.
The Property Screen: Square Footage, Bathroom Ratio and Layout
Start at 1,200 to 1,300 square feet. That is Clara’s floor, and it is smaller than most investors assume — plenty of entry-level three-bedroom stock clears it. More square footage is better, because more square footage means more bedrooms against the same fixed costs.
The ratio that actually governs the deal is people to bathrooms. Three residents per bathroom is the preferred number. Four to one is the ceiling, not a target. Push past that and you generate turnover, which costs more than the extra room earns.
Bedroom count is something you can manufacture. Dining rooms convert. Garages convert. What you cannot do is convert every common space — you must leave at least one room where residents can watch a movie or play cards. Clara is emphatic that this is not a nicety: when residents get along, length of stay doubles and triples, and PadSplit’s own data backs her on it. The common area is a revenue asset, not wasted square footage.
Run through the screen in this order:
- 1,200+ square feet, more is better
- 3:1 residents per bathroom, 4:1 absolute maximum
- At least one preserved common area after conversions
- Convertible dining room, garage or bonus space to add bedrooms
The consequence is that the old rule flips. Investors traditionally bought small starter homes because bigger, nicer houses did not cash flow against purchase price. Under this model they can. One of Clara’s students bought a South Carolina property that looked like a mansion from the street, configured it at 13 bedrooms and 8 bathrooms, and reports roughly $60,000 a year in free cash flow from the single asset.
I’m always saying work with the rule, not against it. Use multifamilies that have four bedrooms and stack them up, instead of doing a house with twelve people in it.

Where Co-Living Rental Investing Works: Transit, Job Centers and Market Selection
Location screening runs on two distances. First, the property should be within about a mile walking distance of public transportation — a meaningful share of this resident base does not own a car and is not going to. Second, it should be within a 20 to 25 minute drive of a concentration of work or study: a university, a hospital, a military base, an Amazon warehouse, a distribution cluster. Where those two conditions overlap, the demand exists.
Clara’s position on market selection is blunt: there is no market where this does not work. Her demand estimate is roughly 60 million Americans who either cannot afford a studio or earn under $40,000 a year. Add students, young professionals and shift workers on top of that, weighted by the profile of the city.
The markets currently absorbing the most room supply are not the expensive coastal ones. Atlanta is PadSplit’s headquarters and one of its strongest markets. Las Vegas works. So does Georgia broadly, Dallas, Houston, Charlotte, and the Florida corridor from Tampa through Jacksonville and around Orlando.
Boston, New York, Chicago, San Francisco and Los Angeles were the first wave — the venture-backed era a decade ago, built on multifamily arbitrage rather than ownership. Those markets have since fragmented into smaller owner-operators and platform-based booking. The capital-intensive arbitrage model is not what is scaling now.
The practical read for an investor with existing rentals: do not disqualify your market. Disqualify individual properties that fail the transit and job-center test. A house 40 minutes from anything with no bus line is a bad co-living asset in Atlanta and a bad one in Boston.
Tenant Profile, Lease Terms and Keeping Rooms Full
The core resident is 18 to 35 — students, young professionals, minimum-wage retail and shift workers, people between life stages. Mike Hambright had roommates until he married at 30, and that window is the market.
On lease length, Clara’s Massachusetts minimum is four months and the average actual stay is nine, shaped by the school calendar. PadSplit reports a national average of eight to nine months. Offering a four-month minimum does not mean you turn rooms every four months.
The counterintuitive part is pricing. Residents pay a premium for flexibility, not a discount. The room is furnished, all utilities are included, internet is included, and in many products trash and lawn are too. Against that bundle, and against not being locked into a twelve-month lease with break fees, they will pay more per square foot than a conventional tenant.
Retention runs on what Clara calls the three Cs — cost, community, convenience — and the last one is where most owners underinvest. Convenience means asking what your specific resident needs and buying it:
- A real desk and a real chair if they work or study from home
- Kitchen capacity that actually supports five or six people — counter space, pantry space, a second refrigerator, the appliances people currently use
- TVs in rooms, depending on your audience
- Perks that cost the owner little, such as gym memberships or financial-literacy resources
The cheapest occupancy tool is internal referrals. Pay an existing resident a rent credit — $200, whatever fits your numbers — for filling the room next door. They will do it happily, and you will fill vacancies before they ever hit a listing site.
Regulations: Unrelated-Occupant Limits and County-Level Reality
One rule blocks more co-living deals than everything else combined: the cap on how many unrelated adults may occupy a single dwelling. In Massachusetts it is four. In New York it is roughly three. These ordinances trace back to the 1800s and they determine your maximum bedroom count regardless of how much square footage or how many bathrooms you have.
The direction of travel is favorable. Colorado and Washington have moved to repeal their limits, New Hampshire is among the most recent, and Clara counts six or seven states in that column. More significantly, states and cities are beginning to fold co-living into affordable and accessible housing programs rather than fighting it. Jacksonville worked through a legal back-and-forth with PadSplit and landed on fair housing grounds. This is the inverse of what happened to short-term rentals: co-living adds access to housing rather than removing it, and regulators are responding accordingly.
Texas illustrates how granular this gets. Houston has no zoning, which is why purpose-built projects there run to 10-bedroom, 10-bathroom configurations — Clara has seen a 28-and-28 financed and under construction. Elsewhere in Texas it is county by county, and at least one county in the Dallas area is unfriendly. Florida is the same patchwork; Orlando runs closer to 20 people.
Her operating principle is to work with the rule rather than against it. Instead of stuffing twelve residents into one single-family house in a jurisdiction that permits four, buy multifamily and stack compliant three- and four-bedroom units. You get the same room count across the asset without a code violation.
Verify the ordinance yourself, at the county and city level, before you write an offer.
Operations, Property Management and New Construction
Hire property management on a fixed fee per unit, not a percentage of rent. This is Clara’s standing recommendation, and the logic is that co-living revenue per house is high enough that a percentage fee overpays management for work that does not scale with the rent roll. A fixed-fee PM doing volume is, in her words, a no-brainer.
Expect to train them. Most local property managers have never run a rent-by-the-room house and will apply single-family habits to it — wrong lease structure, wrong turnover process, wrong tenant communication. Training the PM is part of the setup cost, not an afterthought.
Benchmark your presentation against Airbnb, not against the rental listings in your market. Prospects shop these rooms the way they shop a short-term stay: photos first, price second. A dirty mattress on a metal frame photographed badly will not rent at any price, and it drags down what the rest of the house can command. Furnish and photograph accordingly.
The highest-performing configuration is a bedroom with its own private bathroom. Private-bath rooms rent for meaningfully more, and Clara reports retention far above shared-bath rooms — closer to a studio with a shared kitchen than to a roommate situation. That is why she now favors purpose-built new construction: five or six suites designed as suites from the start, sometimes with a mini fridge and microwave in the room, occasionally sized for a couple.
For lead generation, PadSplit is the dominant channel. It lists roughly 32,000 rooms today and has stated a target of one million rooms on the platform by 2030.
Frequently asked questions
What square footage and bathroom count does a house need to work as a co-living rental?
Start at 1,200 to 1,300 square feet as an absolute minimum, and more is better because additional bedrooms spread the same fixed costs. On bathrooms, target three residents per bathroom; four per bathroom is the ceiling and will cost you in turnover.
Bedroom count is partly manufacturable — dining rooms and garages convert — but you must preserve at least one common area. Houses where residents socialize hold tenants two to three times longer.
What cap rate and cash-on-cash return should an investor underwrite for co-living?
Clara of Coliving Cashflow cites cap rates north of 8%, with well-bought deals landing at 10, 11 or 12%, and cash-on-cash returns of 15% to 25%. Some operators screen exclusively for 12%-plus.
Build the revenue line from actual room rates in your submarket rather than a whole-house rent estimate. In Dallas, rooms with private bathrooms are renting in the $700 to $1,000 range.
How long do co-living residents typically stay, and what lease length should I offer?
Average stays run eight to nine months. Clara’s Massachusetts houses use a four-month minimum lease and average nine months, and PadSplit reports an eight-to-nine month average nationally.
Offering a short minimum does not shorten actual tenure — it is the flexibility that residents pay a premium for. Furnished, all-utilities-included rooms with no twelve-month lock-in command more per square foot, not less.
Is co-living legal where I invest, and what rule most often blocks it?
The rule that most often blocks it is the local cap on unrelated adults sharing one dwelling — four in Massachusetts, roughly three in New York. Several states including Colorado, Washington and New Hampshire have moved to repeal those limits, but in Texas and Florida it varies county by county.
Verify the ordinance for your specific city and county before buying. Where the cap is restrictive, stacking compliant three- and four-bedroom units in a multifamily building achieves similar room counts without violating it.
Should I use a percentage-based or fixed-fee property manager for a co-living house?
Fixed fee per unit. Because co-living revenue per house is much higher than conventional rent, a percentage-of-rent structure overpays for management work that does not scale proportionally with revenue.
Whichever manager you hire, budget time to train them on co-living specifically. Most local PMs have only run single-family or conventional multifamily and will default to processes that do not fit room-by-room operations.
The bottom line
Pull your rent roll and run every property you own through the screen: 1,200-plus square feet, three residents per bathroom, a mile from transit, 25 minutes from a job or campus concentration, and inside your county’s unrelated-occupant limit. The houses that clear all five are conversion candidates you already own.
